Systems and methods for capturing measurements of images of an object to be measured using a mobile electronic device are disclosed. A method may include capturing a measurement image of a measured object within an observation region of a camera of the device, displaying a light-emitted image on a screen of the device, causing the screen to successively display multiple illumination images of a predefined illumination image sequence, and causing the screen of the device to display one or more of the illumination images of the predefined illumination images. The predefined illumination image sequence is set via a user interface of the device and a selection between different predefined illumination image sequences is rendered using the user interface. A control unit is configured to select a predefined illumination image sequence between several stored predefined illumination image sequences in dependence on a selection of the measured object of interest and/or a characteristic of interest.
Legal claims defining the scope of protection, as filed with the USPTO.
4. The method of claim 3, wherein each of the illumination images fills out only a partial region of the total image area of the screen, and wherein the filled-out partial region of a particular one of the illumination images differs from the filled-out partial region of another particular one of the illumination images in its arrangement on the total image area of the screen.
5. The method of claim 4, wherein the total image area of the screen comprises an upper edge, wherein the filled-out partial region of the particular one of the illumination images and the filled-out partial region of the another particular one of the of the illumination images differ from one another in their distance from the upper edge of the total image area of the screen, and wherein a lens is arranged above the upper edge of the total image area of the screen.
6. The method of claim 1, wherein the camera of the mobile electronic device comprises multiple colour channels, wherein the camera has a channel-specific spectral sensitivity for each of the colour channels, wherein the camera comprises an image sensor which comprises a multiple sensor elements arranged in a grid, wherein each of the colour channels of the camera is formed by a subset of the sensor elements of the image sensor, and wherein a spectral sensitivity of each of the sensor elements of the image sensor correspond to the channel-specific sensitivity of the respective colour channel of the camera.
7. The method of claim 1, wherein the camera of the mobile electronic device includes a red colour channel, a green colour channel, and a blue colour channel.
8. The method of claim 1, wherein the measurement image includes multiple image points and image data which is assigned to the image points.
10. The method of claim 9, wherein the evaluation unit is configured to evaluate the measurement data set using an artificial neural network.
11. A non-transitory machine-readable medium comprising instructions, which when executed by a computing device, configure the computing device to perform the method of claim 1.
14. The Method of claim 13, wherein merging the image points of the measurement image is done by an image registration of the measurement images.
19. The method of claim 18, wherein the evaluation unit is configured to compare the measurement data set with at least one predefined reference data set, wherein the evaluation unit is configured to determine at least one reflection characteristic of the measured object from the measurement data set, wherein the determination of the at least one reflection characteristic uses a spectral sensitivity of the camera and a spectral emission characteristic of the screen, and wherein the evaluation unit is configured to compare the at least one determined reflection characteristic of the measured object with at least one predefined reference reflection characteristic.
20. A non-transitory machine-readable medium comprising instructions, which when executed by a computing device, configure the computing device to perform the method of claim 17.
